Know-How

Inflatable life jackets are effective, reliable and comfortable. However, unlike traditional foam-filled life jackets, they must be properly maintained if they are to function correctly. This goes double for a life jacket with an integral safety harness and/or automatic inflation. Inflatable life jackets include a number of parts that must all work properly if the life jacket is to function at

Anyone who has played with electrical gear for any length of time is familiar with the distinctive smell of burned windings. Unfortunately, this smell, wafting out of engine rooms from fried alternators, may soon become familiar to a much wider audience. Why might alternators, generally known for their reliability, become more likely to fail in the next few years?The answer lies in

There are times when we find exactly what we aren’t looking for, and this was one of them.I was tired of technology and wanted to write a sailing story about the good old days, when a Windex was high-tech and real navigators dealt with celestial fixes and high-anxiety uncertainty. What better place to look for such things than at the annual Annapolis Classic Wooden Boat Regatta? Ambling

As I knelt beside the open cockpit locker of my 36-foot Pearson cutter Sonata, I could hear the gentle whir of my freshwater pump. It didn’t sound normal. I reached down and felt the pump housing. The pump was in constant-cycle mode and running hot. It could pump until it burned out and still fail to pressurize the freshwater system I thought I had just finished

Dorothy Parker once famously remarked: “I hate writing; I love having written.” I feel the same way about varnishing. Nothing flatters a boat more than the glow of well-varnished wood, but to bask in that glow, someone must suffer through the process of preparing the wood and applying the varnish.Almost all woods other than teak will weather and eventually rot if not

This past summer I tested the latest generation of electric outboard motors from Torqeedo. These are much more efficient than traditional electric outboards, but with this advance comes a quantum leap in sophistication and electronic complexity.I find it intriguing that these outboards have been designed by landlubbers. One of the owners of Torqeedo, Dr. Christoph Balin, bought a house on

Jose Viegas of Lagos, Portugal, asks:"I have a Navman DSC VHF radio, and last summer I began noticing that when I transmit in bad weather, only boats close by can hear me. But I can always clearly receive transmissions from others, near and far. How can I test to see whether the problem is with the antenna, the connection or possibly the radio itself?" Tim

A few years ago, I left my boat’s two lead-acid batteries on board over winter. It wasn’t intentional—an early snowfall led me to cover the boat up sooner than anticipated, and I just never got around to taking the batteries off.After three months of freezing New England winter, I suddenly remembered they were still on board. I snuck down to the yard one mild Saturday and hooked the

Jim Liggett of Cornish, New Hampshire, asks:"I am installing a lightning- ground system and plan to use a 5/8in rod extending at least 6in above my VHF antenna. Does it matter whether the pointed rod is solid copper or can it be copper-coated steel, as is often used for grounding rods on shore? If the steel rod will work equally well, is there a good way to keep the tip

Karl Westman of Ocean City, New Jersey, asks:"Is it all right to use magnetic headings on my chartplotter to adjust a new compass?"Tim Bartlett replies:In theory, definitely not. But in practice I'd have to give you a very guarded "maybe." The problem, of course, is that your heading is the direction your boat is pointing in. Your
